Abstract
Abstract Disclosed is an optical transmission cable having one or more cable elements. Each cable element includes a plurality of optical fibers embedded in the outer surface of a plastic layer applied directly over an antibuckling member. When the plastic layer is silicone rubber, the optical fibers may be peeled away from the bundle by hand as desired.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
120 words
An optical transmission cable, comprising: an outer plastic tube; an inner plastic tube within the outer plastic tube; a set of tensile strength members disposed between the outer plastic tube and the inner tube; a plurality of cable elements disposed within the inner plastic tube, each of said cable elements comprising an element anti-buckling member having a longitudinal axis, a plastic layer applied directly over the element anti-buckling member, and a plurality of optical fibers embedded in the plastic layer to a depth at which a portion, but not all, of the longitudinal surface of the optical fibers are not covered by the plastic layer; and, a filling compound filling the interstices between the cable elements and the inner tube.
Claim 2
Dependent Claim
120 words
An optical transmission cable, comprising: an outer plastic tube; an inner plastic tube within the outer plastic tube; a set of tensile strength members disposed between the outer plastic tube and the inner tube; a plurality of cable elements disposed within the inner plastic tube, each of said cable elements comprising an element anti-buckling member having a longitudinal axis, a plastic layer applied directly over the element anti-buckling member, and a plurality of optical fibers embedded in the plastic layer to a depth at which a portion, but not all, of the longitudinal surface of the optical fibers are not covered by the plastic layer; and, a filling compound filling the interstices between the cable elements and the inner tube.
